Valve Seat Material

Valve Seat Material

Valve seat materials include a wide variety of metals like stainless steel and Inconel, and non-metals like PTFE and PEEK. The best material depends on the specific application’s temperature, pressure, and chemical exposure requirements. For instance, soft seats like PTFE are common for chemical compatibility and bubble-tight seals, while metal seats made of stainless steel or alloys are used for high-pressure, abrasive fluids, or high-temperature applications.

Description

Valve seal materials include a variety of non-metal options like PTFE, Nitrile rubber, and EPDM, as well as metal options such as brass, stainless steel, and graphite, with the specific choice depending on factors like temperature, chemical exposure, and pressure requirements. Common choices include PTFE for high chemical resistance, Nitrile rubber (NBR) for general-purpose applications, and materials like graphite or PEEK for high-temperature or high-pressure scenarios.
